You have a place in your XML document type for (e.g. hex-encoded)
BLOBs to be included or referenced.  Each BLOB in turn should be an
encoding of something using one of a delimited set of more-or-less
standard encodings.  You want to allow or require document authors to
signal which encoding they're using.

The standard example is images, where the encodings might be png, svg,
etc.

Hope this helps,
